Patented Jan. s, 1907. j

To all whom t may concern' lBe it known ,that we, WALTER S. TURPIN andJONAs H. HOLDEN, residing at Washington, in the District of Columbia, have invented certain new and useful VImprovements in Universal Joints 5 and wel do hereby declare the following to be a full, clear, and exact description of the invention, such as 'will enable others skilled in the art to which it appertains to make and use the same. f

The present invention relates to universal joints of the type comprising suitable vcoupling-heads and an interposed connectingblock or binding-piece pivotally secured to the coupling-head.v j

The object of our invention is to provide a universal joint of the type referred to of i1nproved construction, particularly as to ther means for pivotally securing the connectingblock or common binding-piece to the coupling-head, also to provide a means of preventing the arms of the forked members Y and, third, to provide a means of adjusting and locking the pivot.

With this object in view our invention consists of the universal joint hereinafter described and claimed, the advantages of which will be apparent to those skilled in the art from the following description.

Our invention will be clearly understood from the accompanying drawings, in which is illustrated ya universal joint embodying our invention in its preferred form.

In said drawings, Figure 1 is a view in side elevation of the universal joint. Fig. 2 is a cross-section along a median horizontal line, and Fig. 3 is a transverse cross-section through the pivots.

1 and 2 represent the coupling-heads of any suitable construction, secured to or formed integral with the two shafts.y (Not shown.) Between the forked ends of the couplingheads is interposed a connecting-block o'r common binding-piece 3, which is pivotally secured to the coupling-heads or forked members. For pivotally securing the connectingblock or common binding-piece to the coupling-heads our invention contemplates the use of sleeves or bushings passing through the forked ends of the cou ling-heads and screwing into the connecting-block or commonbindingpiece, and to prevent these bushings or sleeves from working out our invention contemplates the use of pins passing centrally through the sleeves or bushings and also screwing into' the connecting-block with a thread of the oppo.

- or countersunk'at the top to take a ta ered or flange-headed pin, asshown in the rawvings and indicated by 5,'7, 9," and 11. The friction of these pins, together with the fact that the pitch ofthe threads on the pins 5 ,f 7, 9, and 11 and that on the sleeves 4, 6, 8, and 10 are different or that one is right-handed andthe other is left-handed, effectually prevent the sleeves from backing out or screwing up, thus locking any adjustment previously made. By allowing some clearance for the sleeves at the bottom of their holes in the connecting-block wear and lost motion may be taken up by backing out the pins 5, 7, 9, and 11 and setting up on the sleeves 4, 6, 8, and 10 and then relooking them by means of the above-mentioned pins 5, 7 ,-9, and 11.

The block 3 is preferably rectangular in crosssection and has a sufficient extent of surface in contact with the inner surfaces of the forks of the coupling-heads to relieve the pivotsleeves and pins of substantially all strain.

The joint above described is of simy le and inexpensive construction and is relia le and efficient in operation. All the various parts can be made and finished before assembling and the four sleeves and 'four pins should be alike and interchan eable. The joint is then assembled and t e four sleeves set up to allow any desired clearance, and then the pins inserted and set up securely, thus locking the sleeves and preventing themfrom backing out or ti htenin up.

Having thus escribe our Invention, we u claim as new anddesire to secure by Letters Patent of the UnitedStates- 1. A universal joint. havin in combination, coupling-heads, a bloc bindingiece interposed between the coupling-heads, and sleeves or bushings screwing into the block, pivotally connecting the block with the coupling-heads, substantially as described. i
